When you connect to Microsoft SQL Server from the Active Server Pages (ASP) using ActiveX Data Objects via named pipes, the client computer must be validated by SQL Server to use the named pipe. If SQL Server is on a different physical computer than the ASP files, the Active Server Pages might fail. By default, Internet Information Server (IIS) attempts to connect to the SQL Server anonymously. To do this, it uses the anonymous logon information provided in Internet Service Manager (Inetmgr.exe). Typically, this is in the form of IUSR_ MachineName where MachineName is the name of the server that hosts IIS.
